Cement rotary kiln for preventing high temperature deformation

Abstract

This utility model relates to the field of cement rotary kiln technology and discloses a cement rotary kiln for preventing high-temperature deformation. It includes a base, with a support frame fixedly connected to the inner wall of the base. A fixed chamber is fixedly connected to the outer wall of the support frame. A motor drives a reciprocating screw to rotate, causing the stirring blades to turbulently move the coolant, preventing the coolant from flowing slowly when the outer wall of the chamber rotates. Furthermore, the rotation of the chamber can displace the rotating sleeve, allowing it to collect coolant during lifting and then spray it out during subsequent rotation, ensuring greater heat dissipation over a larger area. The rotation of the reciprocating screw also causes the limited slider to displace, which in turn moves the connecting plate and the actuating plate, allowing the actuating plate to better mix and agitate the coolant, further promoting the flow and mixing of the coolant within the base and improving the overall heat dissipation effect.

Description

Technical Field

[0001] This utility model relates to the field of cement rotary kiln technology, specifically to a cement rotary kiln that prevents high-temperature deformation. Background Technology

[0002] A cement rotary kiln is a type of rotary kiln. Its main function is to process cement and lime. In the building materials industry, rotary kilns are used in the production of refractory materials to calcine raw materials, thereby stabilizing their dimensions and increasing their strength before further processing and shaping.

[0003] According to a public notice (Announcement No.: CN219531615U) regarding a cement rotary kiln designed to prevent high-temperature deformation, the aforementioned application, through the installation of a mechanism to prevent high-temperature deformation, facilitates the circulation of water within the cement rotary kiln body via a circulating condenser, thereby facilitating cooling of the kiln's interior and preventing deformation caused by high internal temperatures. The conductive cooler further cools the water in the storage tank, resulting in improved cooling performance of the circulating condenser and extending the service life of the cement rotary kiln.

[0004] However, in actual use, although the above-mentioned equipment can dissipate some heat through the internal water pipes, the heat carried out by the flowing water is limited, and the metal of the machine body still conducts heat very quickly, resulting in the problem that the external metal of the machine body cannot dissipate heat efficiently when in contact with the air; in view of this, we propose a cement rotary kiln to prevent high-temperature deformation. Utility Model Content

[0005] The purpose of this invention is to provide a cement rotary kiln that prevents high-temperature deformation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cement rotary kiln for preventing high-temperature deformation, comprising a base, a support frame fixedly connected to the inner wall of the base, a fixed chamber fixedly connected to the outer wall of the support frame, an external feed inlet provided on the outer wall of the fixed chamber, an external combustion port provided on the outer wall of the fixed chamber, an external discharge port provided on the outer wall of the fixed chamber, a motor fixedly connected to the outer wall of the base, the output end of the motor passing through the base and fixedly connected to the rotary chamber, a cooling assembly provided on the inner wall of the base, the cooling assembly including an external circulation pipe provided on the outer wall of the base, a spacer fixedly connected to the outer wall of the base, a motor fixedly connected to the outer wall of the spacer, and a reciprocating screw fixedly connected to the output end of the motor passing through the spacer.

[0007] The stirring blade is fixedly connected to the outer wall of the reciprocating lead screw. A slider is slidably connected to the outer wall of the reciprocating lead screw. A connecting plate is fixedly connected to the outer wall of the slider. A toggle plate is fixedly connected to the outer wall of the connecting plate. A rotating sleeve is fixedly connected to the outer wall of the rotating chamber.

[0008] Preferably, the transfer chamber is rotatably mounted on the outer wall of the fixed chamber, so that the transfer chamber can rotate smoothly.

[0009] Preferably, the outer wall of the support frame is adapted to the outer wall of the transfer chamber, so that the transfer chamber can rotate smoothly on the outer wall of the support frame.

[0010] Preferably, the number of the toggle plates is several, and the several toggle plates are arranged in a linear array on the outer wall of the connecting plate.

[0011] Preferably, the outer wall of the slider is adapted to the inner wall of the spacer, so that the slider can be limited to move linearly back and forth.

[0012] Preferably, the outer wall of the actuating plate is provided with a dispersing component, the dispersing component includes a mounting frame, the mounting frame is fixedly connected to the outer wall of the actuating plate, and a wire brush is fixedly connected to the outer wall of the mounting frame.

[0013] Preferably, the number of wire brushes is several, and the several wire brushes are arranged in a linear array on the outer wall of the mounting frame.

[0014] Compared with the prior art, this utility model provides a cement rotary kiln that prevents high-temperature deformation, and has the following beneficial effects:

[0015] 1. This cement rotary kiln designed to prevent high-temperature deformation operates by starting the motor, which drives the reciprocating screw to rotate. This causes the agitator blades to turbulently flow the coolant, preventing it from being in a slow-flowing state when rotating the outer wall of the kiln. Furthermore, the rotation of the kiln causes the rotating sleeve to shift, allowing it to collect coolant during lifting and then spray it out during subsequent rotation, ensuring greater heat dissipation over a larger area. The rotation of the reciprocating screw also causes the limited slider to shift, which in turn moves the connecting plate and the agitator plate. This allows the agitator plate to better mix and agitate the coolant, further promoting the flow and mixing of the coolant within the base and enhancing the overall heat dissipation effect.

[0016] 2. In this cement rotary kiln designed to prevent high-temperature deformation, the mounting bracket and wire brush move as the displacement of the actuating plate further promotes the flow rate of coolant in the base. This allows the wire brush to sweep away the coolant sprayed out by the rotating sleeve, thus enabling the coolant to be better distributed on the outer walls of the rotating and fixed chambers, ultimately improving the overall heat dissipation effect and practicality.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a cement rotary kiln to prevent high-temperature deformation, including a base 1, a support frame 2 fixedly connected to the inner wall of the base 1, a fixed chamber 3 fixedly connected to the outer wall of the support frame 2, an external feed port 4 provided on the outer wall of the fixed chamber 3, an external combustion port 5 provided on the outer wall of the fixed chamber 3, the external combustion port 5 can be inserted into a burner, thereby adjusting the injection direction and speed of pulverized coal, so that the pulverized coal and air are fully mixed to achieve efficient combustion, an external discharge port 6 provided on the outer wall of the fixed chamber 3, a motor 10 fixedly connected to the outer wall of the base 1, the output end of the motor 10 passing through the base 1 and fixedly connected to a rotating chamber 7, a cooling assembly 8 provided on the inner wall of the base 1, the cooling assembly 8 including an external circulation pipe 801, the external circulation pipe 801 being disposed on the outer wall of the base 1, a spacer 802 fixedly connected to the outer wall of the base 1, a motor 803 fixedly connected to the outer wall of the spacer 802, and a reciprocating screw 804 fixedly connected to the output end of the motor 803 passing through the spacer 802.

[0024] Furthermore, the stirring blade 805 is fixedly connected to the outer wall of the reciprocating screw 804, the outer wall of the reciprocating screw 804 is slidably connected to the slider 806, the outer wall of the slider 806 is fixedly connected to the connecting plate 807, the outer wall of the connecting plate 807 is fixedly connected to the actuating plate 808, and the outer wall of the rotating chamber 7 is fixedly connected to the rotating sleeve 809.

[0025] In this embodiment of the utility model, the rotating chamber 7 is rotatably mounted on the outer wall of the fixed chamber 3, so that the rotating chamber 7 can rotate smoothly. The outer wall of the support frame 2 is adapted to the outer wall of the rotating chamber 7, so that the rotating chamber 7 can rotate smoothly on the outer wall of the support frame 2. The number of actuating plates 808 is several, and the several actuating plates 808 are arranged in a linear array on the outer wall of the connecting plate 807.

[0026] Furthermore, the outer wall of the slider 806 is adapted to the inner wall of the spacer 802, so that the slider 806 can be limited to move linearly back and forth. The outer wall of the actuating plate 808 is provided with a distribution component 9, which includes a mounting frame 901. The mounting frame 901 is fixedly connected to the outer wall of the actuating plate 808. A wire brush 902 is fixedly connected to the outer wall of the mounting frame 901. The number of wire brushes 902 is several, and the several wire brushes 902 are arranged in a linear array on the outer wall of the mounting frame 901.

[0027] In this invention, during daily use, an appropriate amount of coolant can be injected into the base 1, and then a circulating chiller can be connected to the external circulation pipe 801. This allows for the control of the fixed chamber 3 and the rotating chamber 7 for processing and production. When the motor 10 drives the rotating chamber 7 to rotate, the motor 803 can be started. The motor 803 drives the reciprocating screw 804 to rotate, causing the agitator 805 to turbulently flow the coolant, preventing the coolant from being in a slow-flowing state when the outer wall of the rotating chamber 7 rotates. Furthermore, during the rotation of the rotating chamber 7... When rotated, the rotating sleeve 809 can be displaced, allowing it to collect coolant during lifting and spray it out during subsequent rotation, ensuring a larger area of ​​heat dissipation during rotation. When the reciprocating screw 804 rotates, the limited slider 806 is displaced, which in turn causes the connecting plate 807 and the actuating plate 808 to be displaced, allowing the actuating plate 808 to better mix and agitate the coolant, thereby further promoting the flow and mixing effect of the coolant in the base 1, and further improving the overall heat dissipation effect.

[0028] When the displacement of the actuating plate 808 further promotes the flow rate of coolant in the base 1, the mounting bracket 901 and the wire brush 902 will move, so that the wire brush 902 can sweep the coolant sprayed out by the rotating sleeve 809, thereby allowing the coolant to be better distributed on the outer walls of the rotating chamber 7 and the fixed chamber 3, ultimately improving the overall heat dissipation effect and practicality.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
